Matters needing attention in CNC machining

With the advent of the industrial 2.0 era, China’s manufacturing industry is generally growing, and the requirements for the processing and manufacturing industry are higher. Taking the aluminum parts processing and manufacturing industry as an example, the CNC machining accuracy of aluminum alloy is more stringent. However, this is also the trend of the times. It is obvious that aluminum parts are widely used in high-precision instruments. Now we talk about the matters needing attention in CNC machining of aluminum alloy.

1. The speed of white steel knife should not be too fast.
2. When the workpiece is too high, please thicken it with a knife of different grade length.
3. After roughening with a rough knife, remove the excess with the knife, and grind the knife after ensuring the excess.
4. The plane is processed with flat bottom edge instead of ball edge to reduce processing time.
5. The four corners of the calibration plane must be flat.
6. The inclination is an integer, which is processed with an inclined cutter, such as tube position.
7. Before each work, want to clear the remaining amount of the previous work after processing, to avoid empty tool and redundant processing.
8. Try to take a simple path. For example, shape, trenching, avoiding single side, lapping, etc.
9. When taking wcut, if you can go to finish, please don’t take rough.
10. In the case of shape light knife, the light should be coarsened first and then exposed. When the workpiece is too high, it should be illuminated first and then.
11. The tolerance should be set reasonably to balance the machining accuracy and computer calculation time. The tolerance is set to 1 / 5 of the remaining value when it is turned on, and 0.01 for a light knife.
12. Add more projects to reduce the time of empty knife. Think more and reduce the chances of mistakes. Increase the auxiliary surface of the auxiliary line slightly to improve the processing condition.
